From 2026, the FIA Formula Regional European Championship will adopt the new Tatuus T-326, marking the introduction of the second generation of Formula Regional cars.


Monza, 24 October 2025

At the Temple of Speed in Monza, the brand-new Tatuus T-326 was unveiled. The single-seater that will take centre stage in the FIA Formula Regional European Championship, organized and promoted by ACI, starting from 2026.

The result of an intense development effort by Tatuus Racing, the T-326 (subject to FIA homologation) represents the second generation of Formula Regional cars, marking the evolution of the previous T-318, which since 2019 has accompanied the rise of many talented drivers such as Andrea Kimi Antonelli, Gabriel Bortoleto, Isack Hadjar and Franco Colapinto on their path towards the higher echelons of motorsport.

Aerodynamics and Performance

Developed in full compliance with the latest FIA regulations, the T-326 brings a major step forward in terms of performance, aerodynamics, and safety. The new car has been designed to be lighter, more stable, and more responsive, featuring an improved chassis architecture and a revised suspension system that enhances steering precision and overall balance through corners. Aerodynamic efficiency, inspired by the latest trends from top-level single-seater series, ensures increased overall downforce and reduced wake effect, improving overtaking opportunities and on-track racing quality. From 2026, the Championship will adopt Pirelli tyres as single supplier, fitted on new 15-inch OZ wheels, ensuring technical continuity and uniform performance across the grid.

ATM163T Engine: Power, Efficiency and Innovation

The T-326 will be powered by the brand-new ATM163T engine, developed by Autotecnica Motori and derived from the Toyota G16E unit. This represents the first three-cylinder engine ever introduced in Formula Regional history, developed in collaboration with TOM’S to deliver high performance combined with improved energy efficiency and reliability. The project fully aligns with the new FIA standards for sustainability and technological innovation.


Safety and Ergonomics at the Core

The next-generation chassis complies with the highest FIA safety standards, featuring reinforced structures and updated components such as new-design front and rear crash boxes, anti-intrusion panels, and a revised roll-over protection system. Inside the cockpit, the ergonomic configuration has been optimised to ensure a comfortable driving position suitable for a wide range of drivers, improving visibility, comfort, and overall driving experience.

Technical Partnerships

The T-326 has been developed in collaboration with a strong network of top-tier motorsport partners: ARS Tech, Giga Composite, Carbonmade and La Compositi for carbon fibre components; Breda Racing, Eibach and Andreani for the suspension system; PFC Brakes and Tilton for the braking system. On-board electronics have been developed in partnership with Marelli, Next Solution and Nope Engineering, while the package is completed by the Sadev SLR-82 gearbox, Sabelt harnesses, OMP safety systems, and components from Galletto and Gieffe, forming a technical platform of absolute excellence.

Following an initial testing phase between August and October involving several professional drivers and test specialists, the new Tatuus T-326 is now ready to take to the track. Its official debut in 2026 will mark the beginning of a new chapter in the history of the category, reaffirming its mission to nurture the next generation of international motorsport talents.

Weekend Preview: Brno, Hockenheim and Puebla Write the Next Chapters of the Tatuus Season
Weekend Preview: Brno, Hockenheim and Puebla Write the Next Chapters of the Tatuus Season
From the penultimate round of the F4 CEZ to the FREC finale, via a new round of NACAM, Tatuus cars are preparing for a race weekend spread across three very different venues.


Each event brings something different: for some, it is time to defend an advantage; for others, an opportunity to reshuffle the order, while others can seize the chance to take a step forward and build momentum in their respective campaigns. From F4 CEZ to FREC and F4 NACAM, the upcoming weekend will once again bring together very different championships and racing environments, all featuring Tatuus single-seaters on track.


FREC

Hockenheim will host the final round of the 2026 FIA Formula Regional European Championship, with four drivers still in contention for the title. On the 4.574 km German circuit, the final 56 points of the season will be up for grabs, with Emanuele Olivieri (R-ace GP) leading the standings, Sebastian Wheldon (MP Motorsport) 20 points behind, Kean Nakamura-Berta (PREMA Racing) 25 points off the lead and Rashid Al Dhaheri (R-ace GP) 35 points adrift.

Olivieri’s position is the result of a season built primarily on consistency. The Italian driver has scored eight podiums in the 17 races held so far, including two wins, five second-place finishes and one third place. His victory at Imola, his second of the season after Monza, also allowed him to secure the Rookie title one round early.

Behind him, Wheldon has built his campaign around three victories, two of which came in the same weekend at Zandvoort, along with a win at Paul Ricard. Nakamura-Berta has also claimed three victories and led the standings before the Imola round, while Al Dhaheri occupied the top spot midway through the season before adding his third win in Hungary.

The picture remains particularly open when looking at the championship as a whole: five different drivers have led the standings and there have been no fewer than ten different race winners across the 17 races held. Among them is Oleksandr Bondarev (Van Amersfoort Racing) , who converted pole position into victory on his category debut at Imola. The Ukrainian driver will be back on the grid at Hockenheim, while Reno Francot (CL Motorsport), Salim Hanna (PREMA Racing), Alexandre Munoz (ART Grand Prix), Maksimilian Popov (Trident Motorsport) and Yuki Sano (R-ace GP) complete the list of race winners this season.

Hockenheim will also decide the Team Trophy title, with R-ace GP holding a 106-point advantage over MP Motorsport. It will therefore be the final chapter of a season that has seen the Tatuus T-326 make its first appearance in the FIA Formula Regional European Championship, taking on the category’s major European events.

Weekend schedule:
Saturday, September 12 Qualifying 1 – 09:10 Race 1 – 13:00
Sunday, September 13 Qualifying 2 – 09:40 Race 2 – 16:10

Both Hockenheim races will be broadcast across more than 200 territories and live on the official FIA Formula Regional European Championship YouTube channel.


F4 CEZ

The fifth round of the 2026 season brings the Tatuus T-421 to Autodrom Brno for the penultimate round of the F4 Central European Zone Championship. With 150 points still available between Brno and the season finale at the Hungaroring, the championship remains open to several possible scenarios, starting at the top of the standings.

The top four drivers, from Elia Weiss (Jenzer Motorsport) to Max Karkhan (Jenzer Motorsport) , are separated by just 45 points. Adding further interest to the picture is the fact that five different drivers have won at least one race so far: Weiss has claimed six victories during the season, three of them in the latest round at Autodrom Most. Alongside him, David Walther (Maffi Racing) and Theo Borenstein (Jenzer Motorsport) have each scored three wins, Karhan has two, while Simon Rechenmacher (Cram Motorsport) secured his first championship victory at Slovakia Ring. And the mathematics widens the group even further: nine drivers can still fight for the title.

The size of the entry list also makes Brno a particularly busy event, with the provisional list featuring 36 cars. Free Practice and Qualifying will therefore be split into two groups, while the weekend will feature four races on the 5.4 km circuit.

In the Women’s Trophy, Mathilda Paatz (Mathilda Racing) and Ella Häkkinen (Jenzer Motorsport) are separated by just seven points, while Jenzer Motorsport leads the Teams’ Championship.

Weekend schedule:
Friday, September 11 Qualifying 1 – 15:20 Qualifying 2 – 15:50
Saturday, September 12 Race 1 – 09:35 Race 2 – 14:25
Sunday, September 13 Race 3 – 09:00 Race 4 – 15:05

All F4 CEZ races will be broadcast live on the championship’s official YouTube channel.


F4 NACAM
The Mexico Super Fan will be the next stop on the NACAM Formula 4 Championship calendar, with the series heading to the Autodromo Miguel E. Abed in Amozoc, Puebla, this weekend.

At the wheel of the Tatuus T-421, Alex Bobadilla, Alan Zezatti, Oliver Trejo, Alex Popow Jr. and Fernando Rivera are preparing for a new challenge at the Mexican circuit, with Bobadilla so far showing the most consistent form and therefore emerging as the benchmark of the group.

The young drivers will have two opportunities to fight for victory during Saturday’s programme.

Weekend schedule:
Saturday, September 12 Race 1 – 11:35 Race 2 – 14:35

“Motorsport works like magic, capable of inspiring that uniquely Italian determination to keep believing in something even when the numbers don’t add up.”
“Motorsport works like magic, capable of inspiring that uniquely Italian determination to keep believing in something even when the numbers don’t add up.”
The words of CEO Giovanni Delfino in an interview with la Repubblica.

The CEO of Tatuus, ATM – Autotecnica Motori, and the Korus Group was featured in an interview published today in la Repubblica and written by Irene Saderini. During the conversation, he reflected on some of the most important and defining moments of his career, while also sharing his views on several aspects of the global motorsport industry.
The full interview is available on repubblica.it .

A Personal Journey A central theme of the interview is the CEO’s personal story, which began with his decision to pursue engineering studies and continued through a career marked by bold choices and decisive moments: “I don’t believe in luck; I believe in being able to seize it. When an opportunity comes your way, you have to recognize it. That said, it would be unfair to claim I wasn’t fortunate. I joined the company when I had virtually nothing. The founder allowed me to repay my debt over time, and I only finished paying the last installments two or three years ago.”
Delfino also spoke about his early years at Alfa Corse, where he developed his passion for experimentation and performance engineering: “At heart, I am a track engineer. I worked in the testing departments, where our job was to find that extra half horsepower from a finished product. My first experiences came in Alfa Romeo Touring Cars, with drivers such as Giovanardi, Tarquini and Larini competing against BMW and Mercedes. Sometimes those extra two horsepower were what won you the race.”

Formula 4 and Driver Development Among the key topics discussed was the production of Formula racing cars and engines, today one of the cornerstones of the Korus Group: “Everything starts with studying the regulations, which always leave room for interpretation—and success comes from finding the right one.” Speaking about Formula 4 engines, Delfino explained: “It all starts with a four-cylinder Fiat 500 Abarth unit. It must cost less than €16,500 due to the price cap and last 10,000 kilometres. My objective is to ensure that every engine performs the same.” The reward is seeing young talents progress step by step through the motorsport ladder and ultimately reach the highest levels of the sport: “It was particularly rewarding to see Andrea Kimi Antonelli begin his career in one of our cars.”

The Motorsport Industry The interview also included a broader reflection on the remarkable momentum motorsport is experiencing worldwide: “Motorsport sometimes works like a kind of magic, capable of overcoming marketing logic and keeping alive that uniquely Italian determination to believe in something even when the numbers don’t add up.”
Particularly representative of the Korus Group’s vision was Delfino’s perspective on internal combustion and electric powertrains: “For me, the smell of a winning engine is the smell of gasoline, hard work and sacrifice. A twelve-cylinder engine on track is like a violin—actually, an entire orchestra of violins. Racing is my world, and I find it difficult to see any of that emotion in batteries alone. Hybrid technology, however, is a different story. We are part of the FIA working group on the new regulations, and I find the hybrid approach very compelling.”

Tatuus Celebrates the 500th T-421, the World’s Most Widely Used Formula 4 Car
Tatuus Celebrates the 500th T-421, the World’s Most Widely Used Formula 4 Car
The Lainate-based manufacturer has celebrated the production and delivery of the 500th chassis of the single-seater on which Kimi Antonelli and Arvid Lindblad developed their careers.

Born in 2021, the Tatuus T-421 reached its 500th unit produced and delivered in May 2026, once again confirming its status as one of the most manufactured and successful racing single-seaters worldwide. The milestone was celebrated by the Lainate-based brand together with all its employees and the sister companies of the Korus group, which contribute daily to the T-421 project: ATM–Autotecnica Motori, Breda Racing, and Next Solution Technologies.
Today, the T-421 is the most widely used Formula 4 car in the world, competing across 16 championships spanning Europe, the Americas, Asia, and Oceania. Behind its wheel, some of the most exciting talents in contemporary motorsport have developed, including Kimi Antonelli and Arvid Lindblad , who built the first steps of their single-seater careers in the second-generation Tatuus F4 before progressing all the way to the pinnacle of Formula 1.
“The 500th T-421 is not only a major milestone for Tatuus, but also an important achievement for the entire international motorsport ecosystem,” said Giovanni Delfino, CEO of Tatuus and the Korus Group. “With the introduction of Formula 4 in 2014, the FIA created a new pathway between karting and single-seaters, enabling drivers to arrive better prepared for higher categories. This model has established itself through years of significant growth in motorsport, during which many championships were launched and expanded, now reaching grids of nearly 50 cars per round with the second generation we celebrate today. These are figures that were difficult to imagine at the beginning of this journey, but which now define the everyday reality of many of the companies within the Korus Group.”
“Throughout Tatuus’ history, many of our models have achieved widespread adoption across global championships and have demonstrated unparalleled driver development capabilities,” added Gianfranco De Bellis, President of Tatuus and the Korus group. “The T-421 is writing an important chapter in the history of our brand and, together with the first-generation car, is now approaching 800 units produced. These volumes allow us to aim toward the milestone of 1,000 F4 single-seaters, a figure previously approached by the various Formula Renault models that marked a turning point in our history and in the development path of many drivers.”
As the second generation of Formula 4 single-seaters, the T-421 succeeded the T-014, which from 2014—the year Formula 4 was introduced—through 2021 was produced in just under 300 units. It represented the ideal platform for drivers transitioning from karting to single-seaters, and helped develop talents such as Lando Norris, Oscar Piastri, Max Verstappen, Isack Hadjar, Liam Lawson, Lance Stroll, Oliver Bearman, Gabriel Bortoleto, and Franco Colapinto.
The T-421 is just one of many examples of the cooperation that makes the Korus group one of the leading global ecosystems in motorsport engineering. The companies within the Group involved in the celebration have contributed to the project from day one, within a consolidated model of synergies that each year gives rise to new cars, powertrains, and solutions for motorsport.
Specifically, ATM–Autotecnica Motori developed and supplies the Abarth-derived inline four-cylinder engine that powers the car, while Breda Racing is responsible for a large portion of the components—such as the halo and suspension arms—as well as instrumentation required for managing the cars both on track and at HQ. Next Solution Technologies provides a significant part of the car’s electronic and electromechanical systems, in addition to supplying steering wheels and rain lights.
However, the milestone of 500 cars does not represent a finishing point for Tatuus. Production of the current model will continue through 2028 , when FIA regulations foresee the introduction of the third-generation car , on which the brands of the Korus Group are already actively working.
